Description
P. c. TABOR Jan. 30, 1968 LOCK RELEASE ADJUSTMENT CLIP Filed Oct. 4, 1965 INVENT OR PAUL C. T4501? United States Patent 3,366,416 LOCK RELEASE ADJUSTMENT CLIP Paul C. Tabor, Clawson, Mich., assignor to Rockwell- Standard Corporation, Pittsburgh, Pa., a corporation of Delaware Filed Oct. 4, 1965, Ser. No. 492,660 10 Claims. (Cl. 297-361) The present invention refers to adjustable length linkages such as are used to operate seat locking devices and like mechanisms, and more in particular to spring clamp means to secure the linkage in each adjusted position.
In a linkage actuated mechanism such as a seat back adjusting and position locking'device it often becomes necessary to vary the length of the actuator linkage to compensate for manufacturing tolerances, wear or structural requirements, and usually the linkage had to be replaced with one of suitable length.
The present invention eliminates the need for an inventory of different length linkages and provides a variable length linkage which is easily adjusted to suit any condition and is fully efficient in all adjusted positions.
Since relatively large pulling or pushing forces have to be transmitted through such linkage, any length adjusting device of this kind must necessarily establish a solid motion transmitting connection after each adjustment. This is accomplished in the invention by the provision of a special friction lock clamping device which securely clamps two relatively adjustable members of the adjusting linkage together as a unit. This clamping action can be overcome only by deliberately applied manual force during adjustment, but immediately after release of the manual force the clamping action is automatically restored due to a spring force incorporated in the clamping device.
Accordingly, the main object of this invention is the provision of an adjustable length linkage for a mechanism actuator and a novel locking and clamping device therefor which is so constructed and associated with the linkage that normally a solid motion transmitting connection is provided between adjustable members of the linkage which can only be overcome by deliberately applied manual force, but which, however, again locks the adjustable members together immediately upon release of the manual unlocking force.
Another object resides in the provision of an adjustable rod linkage in which two side-by-side separate rod members otherwise movable longitudinally with respect to each other are securely held against such movement by a spring loaded clamping device which frictionally grips both rod members.
A further object is the provision of a novel friction clamp of special construction and made of spring steel or the like to hold two otherwise relatively movable side-by-side rod members together as a unit so that if either a pushing or a pulling force up to a predetermined magnitude is exerted on the unit it will not change in length.
A further object of the invention is to provide a novel V-shaped spring metal clamp for releasably holding two side-by-side members in relative longitudinal positions.
Other novel features and advantages will become apparent from the following detailed description in connection with the appended drawings in which:
FIGURE 1 is a side elevation partially broken away and showing a vehicle seat frame assembly with an adjustable back mechanism having an adjustable actuator linkage for that mechanism according to a preferred embodiment of the invention;
FIGURE 2 is a sectional view showing one form of the adjustable lock mechanism of FIGURE 1;
FIGURE 3 is a fragmentary enlarged view of the spe- Patented Jan. 30, 1968 ice cial linkage locking device separate from the seat adjusting mechanism of FIGURE 1;
FIGURE 4 is a section through the linkage and lock ing device substantially along line 4-4 of FIGURE 3; and
FIGURE 5 is an enlarged partially sectional view showing the locking clamp device of the invention and its action more in detail.
FIGURE 1 shows a tubular seat frame assembly such as may be used for bucket seats in automobiles. The assembly 10 comprises a seating portion 12 and an associated back rest portion 14 which has adjustable inclination fore and aft relative to seating portion 12. To this effect back rest 14 is hinged at 16 on a bracket 18 welded or otherwise fixed to seat portion 12.
To tiltably adjust the back rest 14 either forwardly or rearwardly, a special linearly functioning adjusting mechanism 20 is provided comprising a tubular housing 22 provided at its upper end with a flange 23 by which it is pivoted at 24 to a rigid transverse rail 25 of the seat back. A rod 26 is longitudinally slidably mounted within housing 22, and at its lower end it projects through the housing wall to terminate in a flange 27 by which it is pivotally attached at 28 to a bracket 29 welded or otherwise secured to bracket 18 forwardly of pivot 16. Internal fixed plates 31 and 32 (FIGURE 2) provide slide guide support for rod 26.
A spring 3-3 within housing 22 surrounds rod 26 and is axially compressed between a flange 34 fixed to rod 26 and the lower end of housing 22 whereby rod 26 is constantly spring biased upwardly in the unit.
A stack of inclined friction lock plates 35 surrounds rod 26 and they are constantly biased into an inclined rod locking position by a coil spring 36, and in this position the lowermost plate of the stack bears against a pin 37 having oifset aligned ends 38 journaled in the housing wall. Housing 26 and plates 35 are of rectangular contour so as to resist relative rotation about the axis of rod 26. Attached to one end 38 of eccentric pin 37 is a release lever 39 which may be manually actuated to rock eccentric pin 37 to tilt the lock plates 35 into non-locking position with respect to rod 26 to enable lengthwise adjustment of the unit 20 by permitting rod 26 to slide longitudinally of housing 22.
The construction and operation of mechanism unit 20 it preferably the same as that of my copending application Ser. No. 376,775 filed June 22, 1964, entitled Adjustable Back Seats, now matured into US. Letters Patent No. 3,271,071 dated Sept. 6, 1966, to which reference is made for more detail. Any suitable lockable mechanism controlled by a release lever such as that at 39 may be used at 20.
The adjustment unit 20 is longitudinally extendable to allow the back rest 14 to be inclined in various selected positions relative to the seat portion 12 and is normally locked to hold the back rest in the last selected position. In order to unlock the adjuster mechanism for changing the back rest inclination, lever 39 is rocked to temporarily release the inner lock at 35, and then release of lever 39 automatically relocks the adjuster unit 20 with back rest 14 in the new position.
The present invention is directed to a novel arrangement for actuating release lever 39 or like lock control element for the unit 20, and it comprises the longitudinally extensible linkage illustrated at 41 in FIGURE 1.
The double rod linkage 41 which is longitudinally adjustable to vary its length comprises the two substantially identical wire rods 42 and 43 which may be of substantially the same length with each of them shorter than the distance between the attaching points of the linkage at the release lever 39 and the bell crank 46.
The free, that is, unloaded condition of the spring clip 51 is indicated in broken lines in FIGURE where it will be seen that the legs 52 and 53 must be compressed towards each other to axially align openings 56 and 57 and allow the rods 42 and 43 to be inserted therethrough in initial assembly. The length of abutment flange 55 is such that when it abuts leg 53, legs 52 and 53 will be parallel.
After the rods have been inserted through the opening and properly distanced longitudinally, manual compression on the spring legs is released allowing the legs to snap back toward their original free position. However, full return is prevented by the rods 42 and 43 which, since they are straight, tend to keep openings 56 and 57 aligned and the spring clip remains loaded With the spring legs gripping the rods.
Under this condition, as illustrated in FIGURE 5, the outer sharp edge 58 of opening 56 in leg 52 bites into the surface of the upper rod 42 and the inner sharp edge 59 of opening 57 bites into the surface of the lower rod 43. Likewise, the outer edge 61 of opening 57 bites into the surface of the upper rod 42 and the inner edge 62 of opening 56 bites into the surface of the lower rod 43. In this fashion, the spring clip 51 firmly locks both rods 42 and 43 together against any relative longitudinal movement in either direction.
The magnitude of the spring force of the clip 51 is such that it renders the clamped linkage strong enough to overcome the resistance afforded by the lock mechanism in the adjuster mechanism at without pulling the rods 42 and 43 apart when a pushing or pulling force is exerted on the hand lever 50.
To release the rods 42 and 43 from being locked 4 together by spring clip 51, manual force by means of a tool such as pliers may be exerted on the legs 52 and 53 to compress them towards each other to the dotted line position of FIGURE 5 to disengage the biting edges of the openings 56 and 57 from the rods and thus free the rods for relative longitudinal movement for length adjusting purpose of the linkage 41. This relative movement can be effected in the disclosed embodiment by rocking lever 50. In the foregoing, unit 20 can be reversed so that rod 26 is connected to the seat back.
When clip 51 is compressed to release the rods for relative adjustment, flange 55 not only serves to determine the optimum release position of the legs 52 and 53 but it prevents overstressing of the legs toward a permanently deformed condition from which it could not return to clamping engagement with the rods.
It will be clear that the above described device may find various other applications besides a seat back rest adjusting mechanism herein shown for illustration purposes only.
The present invention may be embodied in other forms without departing from the spirit and essential characteristics thereof, therefore, the present embodiment is to be considered in all respects as illustrative only and not restrictive the scope of the invention being indicated by the appended claims rather than by the foregoing description.
